Linear Pricing for Artists Explained: Why There Are Two Methods and Which One You Actually Need

If you’ve ever searched for “linear pricing for art,” you’ve probably felt more confused afterward than before. One source tells you to add height and width. Another tells you to add every side twice. Some examples feel inflated. Others feel too low. And no one seems to explain why these formulas exist or when they should be used.

This confusion is not your fault.

Artists are often taught measurement systems borrowed from construction, framing, or installation work… without context. When those systems are applied blindly to painting or illustration, the math can feel wrong because it is wrong for that use case.

This article breaks down the two different linear pricing methods, explains why artists get confused, and shows you when each one makes sense and when it does not. This same distinction is also built directly into how pricing tools like The Art Price Lab approach measurement… because clarity has to come before calculation.

First, What Does “Linear Pricing” Even Mean?

Linear pricing simply means you are measuring length, not surface area.

That’s it.

Unlike square-inch pricing, which measures how much surface you are filling, linear pricing measures how much space something spans. The problem is that length can be measured in more than one way, and both methods are commonly referred to as “linear pricing.”

That lack of distinction is exactly why artists struggle… and why most pricing calculators fail artists instead of helping them.

There are two distinct linear measurement models:

1. Linear span pricing (height + width)

2. Perimeter pricing (height + height + width + width)

They are not interchangeable. They measure different things. And they exist for different reasons.

Linear Span Pricing (Height + Width)

This is the linear pricing method most painters are already using, often without realizing it.

What It Is

Linear span pricing measures the overall scale or footprint of a piece.

Formula
Linear span = Height + Width
Final price = (Height + Width) × Linear rate

Example:
A 20 × 30 inch painting
Linear span = 20 + 30 = 50 inches
At $10 per linear inch
Final price = $500

This is the version of linear pricing that The Art Price Lab treats as the default linear input for painters, because it reflects how image-based work actually occupies space.

What It Measures

Linear span pricing measures:

• visual presence

• physical footprint on a wall

• compositional scale

• how large the piece feels in space

It does not attempt to measure time, detail, or labor directly… and that is intentional.

When Artists Should Use Linear Span Pricing

Linear span pricing works well for:

• oil painters

• watercolor painters

• acrylic painters

• illustrators

• abstract or representational work

• panoramic or elongated formats

• series with consistent height or width

It is especially useful when:

• square-inch pricing feels too rigid

• surface area does not reflect how the work is perceived

• you want a size-based anchor that can be paired with hourly or complexity adjustments

This is why, inside The Art Price Lab, linear span pricing is treated as one input among several, not a standalone answer.

Perimeter Pricing (Height + Height + Width + Width)

This is where most confusion enters.

Perimeter pricing is often introduced to artists as just “another linear option,” but it comes from an entirely different context.

What It Is

Perimeter pricing measures the total edge length of a piece.

Formula
Perimeter = (Height × 2) + (Width × 2)
Final price = Perimeter × Linear rate

Example:
A 20 × 30 inch piece
Perimeter = 20 + 30 + 20 + 30 = 100 inches
At $6 per linear inch
Final price = $600

What It Measures

Perimeter pricing measures:

• edge labor

• finishing work

• sealing and wrapping

• framing or mounting effort

This is not inherently wrong… it is just frequently misapplied.

Where Perimeter Pricing Comes From

Perimeter pricing originates in:

• construction

• framing

• carpentry

• installation

• fabrication

In these fields, every edge is labor. That is why dimensions are doubled. The math reflects physical handling, not image-making.

This is also why The Art Price Lab does not default painters into perimeter-based calculations… because most painters are not building objects.

When Perimeter Pricing Makes Sense for Artists

Perimeter pricing can make sense in specific, edge-driven situations.

Use it only if the edges themselves require meaningful labor.

Examples:

• gallery-wrapped canvases with fully finished sides

• mixed-media or encaustic work with built or sculpted edges

• sculptural wall pieces where edges are part of the visual experience

• framing or mounting labor priced separately from the artwork

In these cases, perimeter pricing works best as:

• a separate line item, or

• an add-on inside a broader pricing structure

This distinction is critical, and it is one of the reasons The Art Price Lab separates measurement from labor protection instead of collapsing everything into a single formula.

When Painters Should NOT Use Perimeter Pricing

Most painters should not use perimeter pricing for the artwork itself.

Avoid it if:

• the work is flat on paper or canvas

• the edges are not intentionally worked

• the piece will be framed or matted by someone else

• most of your labor happens within the composition

• the formula feels inflated or disconnected from effort

That discomfort is not self-doubt… it is pattern recognition.

Why Artists Get Confused About Linear Pricing

This confusion persists for three main reasons:

1. Both methods are called “linear pricing”

2. Most advice never defines what is being measured

3. Artists are taught contractor math without artistic context

When painters are handed formulas designed for builders, the pricing feels arbitrary because the measurement does not match the labor.

This is exactly the gap The Art Price Lab was built to close… by separating measurement, time, and complexity instead of forcing artists to rely on one blunt formula.

The Rule Artists Can Remember

If you remember one thing, remember this:

If your labor happens on the surface, use area or linear span.
If your labor happens on the edges, use perimeter pricing.

For most painters, that means:

• linear span pricing (height + width) is appropriate

• perimeter pricing is an edge case, not a default

How This Fits Into Art Pricing as a Whole

Measurement alone does not equal price.

Linear pricing tells you how big a piece is.
It does not tell you:

• how long it took

• how complex it was

• how many revisions were involved

• how much emotional or cognitive labor was required

That is why sustainable pricing systems combine:

• linear span or square-inch pricing for scale

• hourly pricing for time protection

• minimums and scope definitions for stability

This layered approach is exactly how The Art Price Lab is structured… so artists are not forced to choose between “simple” and “fair.” They can have both.

If linear pricing has ever felt confusing, inflated, or disconnected from your work, you were not misunderstanding the math. You were applying a measurement system that was never designed for your process.

Once you separate linear span from perimeter pricing, everything becomes clearer… and pricing stops feeling like guesswork.
